I am trying to install Keras library using pip in windows 10. I have all the requirements installed, python>=3.8, pip>=20.0.0, NumPy, pandas, matplotlib, virtualenv. But I'm getting the following error.
(keras) C:\Users\namba>pip install keras

I thought this error was caused due to improper installation of h5py & hdf5. I tried installing them using pip install h5py
but then I encountered the following error:

Please suggest any solutions to overcome these errors?
It is preferred to use a 64bit python3(<3.9), to work with deep learning libraries(Keras, TensorFlow), because testings on 32bit were not yet performed and released. So, Make sure you check whether it is 64 bit or 32 bit. Thanks to Tasnuva for helping!
Sometimes it happens due to old version of pip
upgrade pip:
pip3 install --upgrade pip
then try again:
pip install h5py
Note: make sure your python3.8 is 64bit
The following is the procedure I followed to fix the problem.
First, to check which version you're using:
Python vvv 32-bit
)python -VV
from the terminal
